First, the action when starting power supply from from battery 21 to control part 82 describes.
First, the method for the power supply of beginning from battery 21 to control part 82 has following two kinds.
The 1st kind of method is the method for operation window on-off switch 81.
In the time of operation window on-off switch 81, the transistor 221b of trigger circuit 201b connects.In the time that the transistor 221b of trigger circuit 201b connects, the transistor 241b that starts self-hold circuit 203b connects, and then the MOSFET 261b of power-supply circuit 204b connects.In the time that the MOSFET of power-supply circuit 204b 261b connects, start the power supply to control part 82 via fuse 22c and MOSFET 261b from battery 21, window open and close controlling circuit 91 and communication circuit 92 start.
In addition, by the MOSFET 261b of the supply circuit 204b that switches on power, even if the operation of window on-off switch 81 completes, the connection that starts the transistor 241b of self-hold circuit 203b also can continue, and the connection of MOSFET 261b also continues.Therefore,, even if the operation of window on-off switch 81 completes, also can continue to the power supply of control part 82.
Window open and close controlling circuit 91 provides predetermined base current to the transistor 271b of power supply supply lock-out circuit 205b after startup, and transistor 271b is connected.Thus, disconnect even if start the transistor 241b of self-hold circuit 203b, the connection of MOSFET 261b also can continue, and consequently, also can continue to the power supply of control part 82.
In addition, the transistor 291b of switch input circuit 207b connects after window on-off switch 81 is by operation, after the EO of window on-off switch 81, disconnects.And, in the time that transistor 291b connects, the signal of predetermined voltage level (H level) is provided from switch input circuit 207b to window open and close controlling circuit 91, in the time that transistor 291b disconnects, provide the signal of earth level (L level) from switch input circuit 207b to window open and close controlling circuit 91.The serviceability of on/off that thus, window open and close controlling circuit 91 can detection window on-off switch 81 etc.
The 2nd kind of method is to notify the signal of predetermined level from outside (administrative unit 23) to the base stage of the transistor 231b of trigger circuit 202b via order wire, and transistor 231b is connected.
In the time that the transistor 231b of trigger circuit 202b connects, the transistor 241b that starts self-hold circuit 203b connects, and then the MOSFET 261b of power-supply circuit 204b connects.Action is afterwards identical with the situation of operation window on-off switch 81.
Then, for stop from power supply from battery 21 to control part 82 time action describe.
First, window open and close controlling circuit 91 provides predetermined base current to the transistor 281b of self-sustaining cut off 206b, and transistor 281b is connected.Thus, start the transistor 241b disconnection of self-hold circuit 203b.Now, the transistor 271b that supplies with lock-out circuit 205b due to power supply maintains on-state, and therefore, the MOSFET 261b of power-supply circuit 204b also maintains on-state, and the power supply from battery 21 to control part 82 continues.
